STEVAL-ILL069V2

S T E VA L - I L L 0 6 9 V 2 35 W wide input range flyback converter using HVLED001A quasi resonant flyback controller and STF10LN80K5 Data brief Description The STEVAL-ILL069V2 supplies a stable and insulated 48 V voltage bus suitable for secondary side circuitry (e.g., LED current generators) for a total output power of 35 W when a wide range of input voltages is applied at its input. An auxiliary 16 V output is also present to supply small circuits which absorb a maximum current of 20 mA. A very high power factor is obtained thanks to the features of the HVLED001A. Input voltage variations, excessive input voltage (surge or burst overvoltage) or very low input voltages are Features managed by some of the protections of the Input voltage: Vin: 90 - 305 Vrms, f: 45 - 66 HVLED001A, improving the reliability of the Hz application. Output voltage: 48 V / 730 mA The efficiency of the application is very high even High power factor, low THD at very low load thanks to the improved No-load: better than 250 mW 230 Vin frequency fold-back feature that also reduces the Full load efficiency: 90% output voltage ripple at light load. Short circuit protection with auto restart Safety: accordance with EN60065 Output short circuit and overload protections are PCB board: 130 mm x 50 mm single side auto-restart for safe operation in lighting PCB environments.
